Upgrading ClamAV from Source RPM

Prior to rebuilding SRPMs create a seperate account for building RPMs and set up the environment for it:

# su -
# useradd rpmbuild
# su - rpmbuild
# mkdir -p rpm/{BUILD,RPMS/$ARCH,RPMS/noarch,SOURCES,SRPMS,SPECS,tmp}

Replace "$ARCH" with the architecture(s) you plan to build packages.

Then create the minimal "~/.rpmmacros" file with the below contents:

%_topdir               /home/rpmbuild/rpm
%_tmppath              /home/rpmbuild/rpm/tmp

Now we are ready to build RPMs from SRPMs.

1. Download the latest source rpm from dag.wieers.com to the "~/rpm/SRPMS" directory.
   
2. Install the source if you want to further customize the spec file for building the rpm.
   

   $ rpm -ivh SRPMS/clamav-version-release.src.rpm
   

3. Else, rebuild clamav RPM from the source RPM:

   $ rpmbuild --rebuild --define '_without_milter 1' --define \
     '_unpackaged_files_terminate_build 0' SRPMS/clamav-version-release.src.rpm
   

   In my case, I use clamav with MailScanner... so I will not be using clamav-milter for sendmail, so it will build without it.

4. Once the packages are re-built, change to root user and install via:
   

   # rpm -Uvh /home/rpmbuild/rpm/RPMS/$ARCH/clam*.rpm
   

   Which should install clamav, clamav-db, clamav-devel and clamd.

5. Test by updating the virus database and notify clamd if you have it running:

   # /usr/bin/freshclam -v -l /var/log/clamav/freshclam.log --daemon-notify

Customization Notes for MailScanner:

1. With MailScanner only clamav and clamav-db is required.
   
2. Merge the "/etc/freshclam.conf" file with the "freshclam.conf.rpmnew" .
   
3. Removed the daily freshclam cron as MailScanner takes care of updating the ".cvd" database hourly.
   
4. Pointed freshclam logs to go to "/var/log/clamav/freshclam.log" in "/usr/lib/MailScanner/clamav-autoupdate" instead of "/var/log/clamav.log".
   
5. Updated path to freshclam to "/usr/bin/freshclam" in "/usr/lib/MailScanner/clamav-autoupdate" instead of "/usr/local/bin/freshclam".
   
6. Backed up and deleted the old "/etc/clamav.conf" file. Clamav currently uses "clamd.conf" instead.
   
7. Further cleanups of files and folders, left behind from old installs:
   • Deleted old log files "/var/log/{clamav.log,clamd.log}"
     
   • Delete old folders "/var/{run/clamd,lib/clamav}"
     
   • Delete old folder and files in "/usr/share/clamav"
8. `service MailScanner restart`
